Homework Answers
The energy of flow is given by E= y+V^2/2g.
For constant depth y, y as well as V=Q/By is constant.
So the energy of flow is constant.
Hence the correct option is: the energy of the flow is a constant.

Open channel flow must have a surface. Because of the free surface, is the driving force in open channel flow. The application of the equation is most effective to estimate the rapid loss of energy when determining the shape of flow profiles for Rapidly varied flow. Flow in open channels is mainly in the regime. Depth of Flow (y or d) – is the vertical distance of the lowest point of a channel section from the surface. In slope is...
